Do any diesel fuel tank systems direct vent back to the fuel fill?

All the new gasoline fuel fills direct the vent back to the fuel fill as a way of stopping fuel from going into the water.

Other thing, how about normally sealed fuel caps with vapor and pressure relief, similar to a car. The caps vent to the atmosphere on engine fuel demand and when the atmosphere pressure difference exceeds 1 PSI on pressure and less than .25 PSI on suction.
